THROTTLE-CONTROLLING MECHANISM FOR AUTOMOBILES.

Specification of Letters Patent. Patented Mar. 13, 1917.

Application filed September 21, 1916.- Serial No. 121,493.

T hrottle-Controlling Mechanisms for Automobiles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

his invention relates to improvements in automobile controlling mechanisms, particularly to gasolene feed controls.

The principal object of the present inven- 7 tion is to provide a novel and simple mechanism -which will cause the closing of the throttle, completely, by the same movement which applies the brake, and which is especially adapted for use on. Ford automobiles.

Another object of the invention is to provide a novel means for controlling the gasolene feed by hand or foot, each means being arranged to be actuated independently and without interference with the other means.

Another object is to provide a novel means which is adapted to be connected with the brake pedal of the automobile for permitting the automatic closing, to the fullest extent, of the throttle when the brake is being applied.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawings:

Figure lis a top plan view of the frontportion of a Ford automobile, the casing being removed.

Fig. 2 is a side elevation, the casing being removed.

Fig. 3 is a vertical sectional view on the line 33 of Fig. 2.

Fig. 4 is a perspective view of-the brake pedal.

Fig. 5 is a perspective view of the angle arm and supporting bracket therefor.

Fig. 6 is a perspective view of the parts connected with the gas control lever.

Referring particularly to the accompanying drawing 10 represents the throttle to which is ,pivotally connected a link 11 which extends transversely of the front of the automobile. The steering column is represented M12, and carries the usual gas controlling rod 13. The lower end of this rod is formed with an eye 14, through which the beforementioned link 11 is slidably disposed, the said link beyond the eye being formed with a head 15 to prevent the link from passing threthrough in one direction. Secured to the water pipe 16, which leads from the radiator to the engine cylinders, by means of a clamp, is a supporting bracket 17, and mounted on this bracket is a pivotally supported angle lever 18, to one arm of which is pivotally connected one end of a second, but shorter link 19, said link 19 being pivotally connected at its other end to the throttle valve, coincide'ntly with the point of attachment of the first link. The brake pedal 20 is formed with a downwardly projecting extension 20' which is connected to a crank portion 21 of the controlling rod or shaft 22,whiclr has on one end the emergency brake lever 23. A spring 24 connects the brake pedal lever 20 with the chassis of the automobile, and holds the said. pedal normally in rearwardly disposed position. Pivotally connected to the upper portion of the pedal is a forwardly extending link or lever 25, the forward end of which is slidably disposed through an eye 26 formed in the other arm of the bellcrank or angle lever 18, said link being also formed with a head 26 on its forward end to limit its rearward movement through the said eye. A rearwardly extending leaf spring 27 is secured to the forward portion of the chassis and has its rear end connected to the head 15 of thelink 11 by means of a short link 28. The heads 15 and 26 are both adjustable for a purpose which appears later.

It is well known that the throttle valve of the engines of automobiles-do not-entirely close when the control rod is thrown to closed position. Also, on Ford automobiles the gasolene control is accomplished solely by the rod on the steering column, there being no provision for controlling the gasolene by means of the foot. It.is, therefore, the

and novel device which can in the arm of the angle lever 18, and by reasonof the spring 27 and the link which connects it with the link 11, said link 11 will be pushed in the direction of the throttle valve and move the latter into completely closed position. .In normal position, the links head 15 does not engage with the eye of the controlling rod, thuspermitting the said link to slidethr'ough the eye without afli'ecting the position of the controlling rod 13.. Thus the automobile can coast without applying the brakes, and with the engine running.

By a further pressure on the brake pedal the brakes can be applied toretardor stop the car. Thus we have provided a simple be readily applied to the present Ford automobiles, whereby the i can be conveniently controlled by the foot of the operator irrespective of the usual hand control.

What is claimed is:

, 1. "A throttle and an angle member, connections between one arm of the angle memslid able through gasolene supply to the engine brake mechanism for an automobile including a manually operable throttle means,

1 her and the throttle, a brake pedal normally held in inoperative position,

and resiliently the brake pedal and and a link carried by 'slidably connected with the other arm of the angle lever. i

2. A throttle and brake mechanism for an automobile including means for openingand partially'closing the valve, an angle lever operatively connected with the valve and movable therewith, an angularly extending apertured portion on one'end of one arm of the angle lever, abrake pedal having a depending extension, an emergency brake member, connected to the emergency member and the said extension, and a link pivotally connected to thebrake pedal and slidable through the apertured port on of the angle lever, said link being formed with a head for operative the angle lever to move direction.

In testimony whereof, we aflix our signatures in the presence of two witnesses.
